I'm looking to create a new function with the following requirements:
Function add(arr,...newVal){
}
array = [1,2,3];
add(array,0)
console.log(array); //I want this to output [0,1,2,3]
I tried creating the function similar to push like this:
Function add(arr,...newVal){
for(var i=0; i<arr.length; i++){
arr[arr.length]=newVal[i];
}return arr.length;
}
array = [1,2,3];
add(array,4)
console.log(array); // Expected output is [1,2,3,4]
function addToFront(arr, ...newValues) {
let index = arr.length + newValues.length - 1;
for(index; index >= newValues.length; index--) {
arr[index] = arr[index - newValues.length];
}
for(index; index >= 0; index--) {
arr[index] = newValues[index];
}
return arr;
}
Give this a shot:
const addFirst = (array, value) => {
for(let index = array.length; index > 0; index--) {
array[index] = array[index - 1];
}
array[0] = value;
return array;
}
